'Doctor Who' named greatest sci-fi show

Doctor Who has been named the greatest science fiction & fantasy TV show of all time.

The long-running program, which returned to screens in 2005 after a lengthy absence, topped the poll conducted by genre website Totalscifionline.

The site's editor Matt McAllister said: "There have been plenty of mind-bending, thought-provoking SF shows in the history of television, but none have proven as enduring as Doctor Who.

"The key to the show's longevity has been its ability to re-invent itself for new generations while maintaining a consistency in tone and character, and the Daleks and TARDIS have now become part of our cultural landscape. 2010 saw Who head in yet another triumphant direction - surely another 50 years are guaranteed?"
